Example 1 of the control system for home appliances

Referring to Figure 1, a home appliance control system includes:

A locator 101, configured to send a radio frequency signal;

A plurality of positioning terminals 102 arranged in the community are used to receive the radio frequency signal sent by the locator 101 and calculate the distance value with the locator 101, and send each distance value to the community server 103;

Community server 103: used to calculate the position coordinates of the locator 101 through each distance value sent by the positioning terminal, and send the position coordinates to the home server 104 of the corresponding user;

Home server 104: for receiving the position coordinates of the locator 101 sent by the community server 103 and generating corresponding control signals according to the position coordinates 101 to switch the working status of the household appliances.

The locator 101 can be made to be convenient for the user to carry around, such as a wristband, a key chain, etc., and can also be installed in a mobile phone. Each locator 101 is an electronic tag with a unique identification, which is related to the user's home server. Corresponding to 104, the community server 103 sends the location coordinates to the home server 104 of the corresponding user according to the unique identifier of the locator 101 .

The user carries a locator 101 with him, and the locator 101 sends radio frequency signals in real time, and multiple positioning terminals 102 installed in the community receive the radio frequency signals sent by the locator 101 in real time. The distance value of the locator 101, each positioning terminal 102 sends the calculated distance value to the locator 101 to the community server 103, since the locator 101 has an electronic tag with a unique identification, the locator 101 can be calculated according to the identification. From which user's family in the community, the community server 103 calculates the position coordinates of the locator 101 through various distance values, that is, the current position of the user, and sends the position coordinates to the home server 104 in the corresponding user's family.

The home server 104 judges whether the locator 101 is in the community according to the received position coordinates, and the home server 104 compares the position coordinates with the preset community area range, and if the position coordinates fall outside the preset area range, it is considered At this time, the user has left home, the home server 104 generates a corresponding control signal, and the corresponding household appliance receives the control signal and makes it in a low power consumption mode according to the control signal. If the location coordinate falls within the preset area , it is considered that the user returns home, and the home server 104 generates a corresponding control signal to enable the associated household appliances to be in working mode, such as air conditioners, water heaters, etc., and the user will have comfortable temperature and hot water when entering the home.

The preset community area range in this embodiment may be the entire community or a certain part of the community.

The household appliances described in the present invention are all smart household appliances.

The home appliance control system provided in this embodiment calculates the position coordinates of the locator through a plurality of positioning terminals and community servers set in the community, judges the location of the user according to the position coordinates of the locator, and controls the location of the corresponding home user. The working state of household appliances, when the user leaves the community, the household appliances are in a low power consumption mode, which solves the energy waste caused by the user forgetting to turn off the household appliances when going out. When the user enters the community, the household appliances are in the working mode, and when the user returns home Provide a comfortable environment. In addition, when the user is within the preset area, the household appliances are in working condition. Compared with the method of only positioning in the home, it can prevent the user from turning off the household appliances while throwing garbage when going out, reducing the number of household appliances. Switching of working status.

Example 2 of the home appliance control system

Referring to FIG. 2 , the home appliance control system provided in this embodiment includes a locator 201 , four positioning terminals, a community server, a home server, and a home appliance control module.

The locator 201 is an electronic tag with a unique identifier, and the home server in the user's home corresponding to the locator 201 can be identified according to the identifier.

If the position coordinates Falling outside the preset area range, it is considered that the user has left home at this time, and the area determination module 204c generates a corresponding control signal, and the home appliance control module 205 makes the home appliance in a low power consumption mode according to the corresponding control signal; If the coordinates fall within the preset area range, the user is considered to be at home, and the area determination module 204c generates a corresponding control signal, and the home appliance control module 205 puts each home appliance in a normal working mode according to the corresponding control signal, such as an air conditioner, a water heater, etc. Users will have a comfortable temperature and hot water when they enter the home.

The second processor 204b also includes a time determination module 204d, which is used to mark the tag of the locator 201 as unused or in use according to the dynamics of the position coordinates of the locator 201 within a preset time, when the position coordinates of the locator 201 If there is no change within the preset time, the tag of the locator 201 will be marked as unused; when the locator moves again, the tag of the locator 201 will be marked as in use, and the home server will The position coordinates of the switch switch the working state of the household appliances.

For example, if there are 5 locators in the home, but only three are in use, and the two locators have been in a static state, and the position coordinates have not changed within the preset time, then the tags of these two locators are marked as unused, which is useful for home use. The control of electrical appliances is only based on the locator in use. If someone in the family forgets the locator at home, when another person leaves home, the household appliances at home can also enter the low power consumption mode. The preset time can be 24 hours or 48 hours.

Preferably, the community server and the home server communicate based on the zigbee protocol. Zigbee is a new type of short-distance, low-speed wireless network communication technology with low power consumption and low cost.

The home appliance control system provided in this embodiment calculates the position coordinates of the locator through a plurality of positioning terminals and community servers set in the community, judges the location of the user according to the position coordinates of the locator, and controls the location of the corresponding home user. The working state of household appliances, when the user leaves the community, the household appliances are in a low power consumption mode, which solves the energy waste caused by the user forgetting to turn off the household appliances when going out. When the user enters the community, the household appliances are in the working mode, and when the user returns home Provide a comfortable environment; when the user is within the community area and the household appliances are in working condition, compared with the method of only positioning in the home, it can prevent the user from turning off the household appliances while throwing garbage when going out, and reduce the failure of the working status of the household appliances Switching; in addition, the multi-point positioning method can be used to locate the locator more accurately, and compared with the existing GPS positioning, it can effectively lower the cost.
